i followed the real flight plan the airline used. FS flightplanner is not realistic. not unless you do it manualy and follow the realflight plan.
heres a tip: connect waypoint -waypoints

here an example on what i do in making a flight plane
RPLL_RPVM
"B462 MBT W11 batay tubur" thats it! you dont need to put all intersection in the flightplan. i only include two intersection batay and tubur bec. its part of STAR
